Say you get working on a signature adn everything is going well, but you nitice half way downt eh signature that thigns are uneven! Now is the tiem to fix it, don’t think at the end you can manipulatethose threads into working for you- if you’ve done things right and things are tight you won’t be able to move them much!
Let’s say a stich is uneven, and you caught it before you finished that signature was done! Good!
Start my pulling out an inch or two of the thread!
Pull that thread down toward the signatures you have already sewn. Do this gently don’t tear anything now!
After you do that, slowly pull the thread back into the signature, line it up careful as you pull it in. It should line up just right!
